Description

  The present invention relates to a multiple glass shoji provided with a plurality of glass plates.

  Double-glazed glass that is formed by separating two glass plates through a spacer and forming a single hollow layer is excellent in heat insulation and soundproofing, and is widely used in residential and other building windows. Widely used for applications.

  As compared with the above-mentioned type of multi-layer glass, a multi-layer glass in which two glass layers are formed by separating three glass plates through spacers as glass having further improved heat insulation, This is known as Patent Document 1.

  In addition, as a double-layer glass in which the two hollow layers described above are formed, two outermost glass plates are bonded to both sides of one spacer, and another one is interposed between the two glass plates. A multilayer glass formed by fitting and holding a sheet of glass plate in a groove provided inside the spacer is known as Patent Document 2.

  In the double-layer glass having two hollow layers in which three glass plates described in Patent Document 1 are used, in the production, spacers are arranged between the three glass plates, respectively, and a sealing material is used. The work of sealing has to be performed, and the number of parts and the number of assembling processes are large, and the entire thickness of the multilayer glass is increased. For example, when assembling this type of double-layer glass, as shown in FIG. 20, spacers 93, 92 are formed so that hollow layers 92, 92 are formed at the periphery of three glass plates 91, 91, 91, respectively. 93, and a butyl rubber adhesive 94 is applied between the glass plates 91, 91, 91 and the spacers 93, 93, and the glass plates 91, 91, 91 and the spacers 93, 93 A step of filling the outer groove portion 95 with a sealing material such as a polysulfide adhesive or a silicone adhesive and performing a curing process must be performed. When it is going to manufacture the multilayer glass of the multilayer structure which has a hollow layer of 3 layers or more with the above-mentioned structure in the multilayer glass which has the two-layer hollow layer of the structure as described in patent document 1, the number of parts is further increased. There is a problem that the number of assembly steps increases.

  Similarly, in Patent Document 2, a multi-layer glass having a multi-layer structure having three or more hollow layers having the above-described structure is a multiple glass having two hollow layers having the structure described in Patent Document 2. However, there is a problem that the number of parts and assembly man-hours increase further.

  In both of the double-layer glasses (multilayer glass) having the configurations of Patent Documents 1 and 2, when trying to manufacture a multi-layer glass having three or more hollow layers, the number of parts and assembly man-hours increase. There is a problem that it takes time and effort, but neither of Patent Documents 1 and 2 mentions the problem of solving these problems.

  On the other hand, in a double-layer glass of a type in which a single hollow layer is formed, a double-layer glass shoji constructed by placing upper and lower walls and left and right vertical walls between two glass plates arranged at intervals. Is known as Patent Document 3.

  In addition, as a double-glazed shoji structure using double-glazed glass, two glass plates are placed inside the peripheral edge of the glass plate with an internal spacer so that a concave portion is formed inside the peripheral edge between the glass plates. A double-layer glass shoji structure in which a multi-layer glass is formed such that a hollow layer is formed between the two glass plates, and a holding frame is attached to the recessed portion at the peripheral edge of the multi-layer glass. This is known as Patent Document 4.

  In recent years, in energy-saving houses and buildings, with the increasing demand for heat insulation of window openings, four or more glass plates are spaced apart by spacers to form three or more hollow layers. The demand for highly heat-insulating multilayer double-glazed glass has been increased, and the number of parts of such highly heat-insulating multilayer double-glazed glass is reduced, and the assembly man-hours are streamlined, thereby reducing the manufacturing cost. There has been a demand for highly heat-insulating multilayer double-glazed glass having a structure that can be used.

  In addition, it has also been proposed to increase the heat insulation by enclosing more excellent heat insulation gas in the plurality of hollow layers of such a high heat insulation multi-layer glass, but it is optimal for further improving the heat insulation. There is also an increasing demand for selection of the kind of the enclosed gas and optimization of the thickness of the gas layer of the enclosed gas.

  In the case of manufacturing a window shoji using conventional multi-layer glass, for example, a multi-layer glass having a hollow layer in between is manufactured by separating two glass plates using a spacer. Since the double-glazed glass manufacturing process and the double-glazed assembling process of manufacturing the double-glazed glass shoji by assembling the glazing at the peripheral edge of the laminated glass, there are many parts and many assembling steps.

  In addition, in the double-glazed glass using three glass plates described in Patent Document 1, it is difficult to design and manufacture a wall in the periphery of the structure, and the lighting performance, designability and openness are difficult. It was difficult to increase the feeling.

  In addition to the high heat insulation multilayer double-glazed glass for the outer windows of houses and buildings, another inner window is arranged on the indoor side of the outer windows of existing houses and buildings. When using heavy windows to improve soundproofing, heat insulation and crime prevention, the shoji used for the inner window is required to be thinner and lighter. ing.

  In addition, due to the further increase in resource saving, when dismantling houses, buildings, etc., the glass plate placed in the hollow layer can be easily removed from the multiple glass shojis of the type described above removed from their windows. There is also a demand to be able to reuse the removed glass plate.

The illustrated example is a drawing showing a specific example of the lower side portion in the multiple glass shoji, and is a schematic cross section of the lower side portion of the multiple glass shoji as seen from the direction of the arrow of line BB in FIG. FIG. The multiple glass shoji 10 includes a first glass plate 11 and a second glass plate 12, and a frame member 13 disposed between the first and second glass plates, and the first and second glass plates. The hollow layer 14 is formed, and the hollow layer 14 is sealed with a sealing material such as an adhesive or an adhesive around the first and second glass plates. 13 is provided with a plurality of examples of intermediate plate holding portions 16 for holding the end portions of the intermediate plate 15 disposed in the hollow layer 14, and at least one or more intermediate plates 15 are provided in the hollow layer 14. A plurality of examples of intermediate plate holding portions 16 provided in the frame member 13 are arranged, and the hollow layer 14 is divided into a plurality of partitioned hollow layers by the intermediate plate 15. It has become. In the figure, reference numeral 17 denotes a first seal that seals between the side part of the frame member 13 and the side part of the frame member 13 around the first glass plate 11 and the second glass plate 12. A sealing material 18 is a second sealing material that is similarly sealed.

  The intermediate layer formed between the first glass plate 11 and the second glass plate 12 described above, and the first glass plate 11 and the second glass plate 12 by arranging the intermediate plate as described above. A plurality of divided intermediate layers formed between them are referred to as a hollow layer in the present specification, and this hollow layer includes an enclosed gas such as dry air, argon gas, krypton gas, helium gas. Insulating gases such as the above are filled to improve heat insulation and / or soundproofing, and the desiccant contained in the space of the spacer portion of the frame member provides the anti-condensation performance of the multiple glass screen. This hollow layer may be called an air layer, a gas layer, an intermediate layer, or a space layer, and the hollow layer is synonymous with an air layer, a gas layer, an intermediate layer, a space layer, or the like.

  The shape and thickness of the first glass plate 11 and the second glass plate 12 described above are appropriately selected according to the shape and size of the target multiple glass shoji, but for ordinary housing and other structures. In general, it is a rectangular flat glass plate, the thickness of each plate is in the range of 0.7 mm to 10 mm, and the first and second glass plates. The dimensions of 11 and 12 are preferably the same or substantially the same. Further, the first and second glass plates may have different plate thicknesses or different types of glass plates. The types of glass plates are usually float glass plates, ordinary glass plates, heat ray absorbing glass plates, ultraviolet ray absorbing glass plates, heat ray reflecting glass plates, low radiation glass plates (Low-E glass) used for construction. Plate), template glass, laminated glass plate, glass plate with wire / mesh, air-cooled tempered glass plate, chemically tempered glass plate, or a glass plate in which these functions are combined, depending on the desired required specifications It can be used as appropriate.

  Between the first and second glass plates 11 and 12 described above, one sheet that is spaced apart from the glass plates 11 and 12 at a predetermined interval and is arranged in parallel with the glass plates 11 and 12, In addition, the two or more intermediate plates 15 reduce gas convection in the space of the hollow layer 14 between the first and second glass plates 11 and 12, to improve heat insulation and to improve soundproofing performance. It is to be arranged.

  The intermediate plate 15 is arranged on the inner surface side of the frame member 13, that is, on the intermediate layer holding portion 16 provided on the hollow layer side so as to be arranged by an arrangement method such as insertion, fitting, and locking. , 12 is preferably a similar rectangular shape with dimensions smaller than 12. When the 1st and 2nd glass plates 11 and 12 are substantially rectangular shape, the 1st and 2nd glass plates 11 and 12 are spaced apart by the frame member 13 mentioned above in the four sides of the periphery, and are multiplexed. A glass shoji is preferably constructed.

  Since the intermediate plate 15 is disposed between the first and second glass plates 11 and 12 and is not exposed to the outside, the strength requirement may be lower than that of the first and second glass plates. Regardless, it is possible to use a material with a small plate thickness, and therefore it is possible to design a thin overall thickness even with a triple type or multiple type multiple glass shoji. As the intermediate plate 15, a glass plate, a plastic plate, a plastic film or the like can be used. The intermediate plate 15 may be a transparent plate, may be colored, may have a pattern, or may be a combination thereof. As the intermediate plate, an appropriate intermediate plate is used according to the location, part, designability, and the like. When using a glass plate as an intermediate plate, since it is disposed between the first and second glass plates 11 and 12, a glass plate having a thickness of 2 mm or less that can reduce the overall thickness is preferably used. it can. When the intermediate plate 15 is a glass plate, the rigidity is high even if the plate is thin. Therefore, the intermediate plate 15 can be easily inserted, fitted and locked into the intermediate plate holding portion 16, and has transparency and durability. Since it has high property, it is more preferable as an intermediate plate for multiple glass shoji.

  In particular, as the intermediate plate 15, a chemically strengthened glass plate having sufficient strength even if the plate thickness is reduced can be preferably used. The chemically strengthened glass plate is obtained by immersing a glass plate containing a Na component or Li component such as soda lime silicate glass in a molten salt such as potassium nitrate, and / or Na ions having a small atomic diameter present on the surface of the glass plate and / or Glass manufactured using a chemical strengthening technique in which Li ions and K ions having a large atomic diameter present in the molten salt are ion-exchanged to form a compressive stress layer on the surface layer of the glass plate to increase the strength. Even a glass plate with a plate thickness of 2 mm or less has a sufficiently high breaking strength. For example, compared with an ordinary glass plate made of ordinary soda lime silicate glass having a thickness of 2 mm, a chemically strengthened glass plate obtained by strengthening an ordinary glass plate having the same thickness by the ion exchange treatment method described above is about 2 to 10 times. It has a degree of breaking strength. Therefore, if a chemically strengthened glass plate is used as the intermediate plate 15, the intermediate plate of the multiple glass shoji of the present invention can be reduced in weight, and when the multiple glass shoji is manufactured, the intermediate plate can be cracked. Since it can prevent, it is especially preferable. In the case of a chemically strengthened glass plate, it is possible to perform post-cutting by selecting a cutting means or controlling the degree of chemical strengthening treatment. It is possible to select and cut to a predetermined dimension.

  The frame member 13 only needs to have a structure having a function as a spacer portion for separating the first and second glass plates 11 and 12 at a predetermined interval. When the planar glass shape is a rectangular multiple glass shoji, the frame member 13 is arranged on the four sides of the multiple glass shoji upper side, lower side, left side, and right side. More preferably, the frame member on each side basically consists of a single member. That is, the frame member on each side is more preferably basically formed by one member. In addition, a corner member is usually arranged at the abutting portion of the four side frame members of the upper side, the lower side, the left side, and the right side, and the four side frame members of the upper side, the lower side, the left side, and the right side are connected to form a frame shape. The

  The frame member 13 preferably includes a spacer portion having a space portion for storing the desiccant in at least a part of the hollow layer side. The frame member provided with the spacer portion is preferably provided on the four sides of the upper side, the lower side, the left side and the right side, but may be provided on at least one of the four sides of the upper side, the lower side, the left side and the right side. Good.

  Moreover, the frame member 13 may have a vertical saddle part on both the first glass plate side and the second glass plate side of the frame member, or on either one of them.

  In addition, the frame member 13 may have a structure that does not have the spacer portion or the vertical flange portion as described above, and simply has a function of separating the first and second glass plates 11 and 12. .

  When the shape of the planar glass is a rectangular multiple glass shoji, the frame members arranged on the four sides of the upper, lower, left and right sides of the multiple glass shoji are frame members having the same structure on all four sides of the multiple glass shoji.

A communication portion 32 is also formed on the side, and the desiccant stored in the first shared space portion 30 breathes between the partitioned hollow layers 14.

  The insertion and support structure of the intermediate plate 15 in the groove-shaped portion of the intermediate plate holding portion 16 in the example shown in FIG. 8 is the same as that in FIG.

  In the multiple glass shoji 10 of the present invention, a plurality of rows of intermediate plate holding portions 16 are provided on the hollow layer 14 side of the frame member 13. Whether the intermediate plate is arranged using 16 can be appropriately determined according to the required heat insulation performance and the kind of the enclosed gas filled in the hollow layer.

  The example shown in FIG. 9 is an example in which four rows of intermediate plate holding portions 16a, 16b, 16c, and 16d are provided on the hollow layer side of the frame member 13, and among these intermediate plate holding portions, three rows are provided. The intermediate plates 15, 15, 15 are arranged using the groove portions of the intermediate plate holding portions 16 b, 16 c, and 16 d so that four layers of hollow layers 14 a, 14 b, 14 c, and 14 d are formed. It is a thing. This example is an example in which the first glass plate 11 is used so as to be located on the outdoor side of the window, and the first hollow layer 14a disposed on the outdoor side includes the other hollow layers 14b, 14c, It is nearly twice as thick as 14d.

  The example shown in FIG. 10 is an example in which three rows of intermediate plate holding portions 16a, 16b and 16c are provided on the hollow layer 14 side of the frame member 13, and among these intermediate plate holding portions, two rows are provided. The intermediate plates 15 and 15 are arranged using the groove-shaped portions of the intermediate plate holding portions 16a and 16c so that three layers of the hollow layers 14a, 14b and 14c are formed. In this example, the first glass plate 11 is used so as to be located outside the window, and the intermediate hollow layer 14b is nearly twice as thick as the other hollow layers 14a and 14c. Yes.

  In the example shown in FIG. 9 and FIG. 10, the frame member 13 is provided with four or three rows of intermediate plate holding portions, and among the plurality of rows of intermediate plate holding portions 16, an intermediate plate on which the intermediate plates are arranged. Although it is two examples which used the holding | maintenance part selectively, the intermediate | middle board holding | maintenance part provided in the frame member 13 may further be many rows, for example, even if it is about 5 rows-10 rows. The rows of intermediate plate holding portions used for the arrangement of the intermediate plates are not limited to the above example, and various selections are possible. The examples shown in FIGS. 9 and 10 use three rows of the four rows of intermediate plate holding portions and two rows of the three rows of intermediate plate holding portions for the arrangement of the intermediate plates. It goes without saying that the intermediate plate may be disposed using all of them. In FIG. 9, three rows of the four rows of intermediate plate holding portions are used for the placement of the intermediate plates, but two rows of the four rows of intermediate plate holding portions are used for the placement of the intermediate plates. May be. Even when the number of rows of the intermediate plate holding portions is further increased to be a large number of rows, these utilization forms are the same.

  Also, in the case where multiple rows of intermediate plate holding portions are formed on the frame member, the interval between the intermediate plate holding portions is made narrower to make a larger number of rows, and the space layer with the desired thickness is selectively used. It is preferable to increase the range of selection of the intermediate plate holding portion used for the arrangement of the intermediate plate so as to be formed.

  The example shown in FIG. 11 is an example in which a plurality of rows of intermediate plate holding portions are provided on the frame member so that the number of rows for selecting the intermediate plate holding portions used for arranging the intermediate plates is increased. In the figure, an example in which seven rows of intermediate plate holding portions 16a, 16b, 16c, 16d, 16e, 16f and 16g are formed on the frame member 13 is shown.

  In FIG. 11, the positions of the groove-shaped portions of the intermediate plate holding portions 16 a to 16 g provided on the frame member 13 are intervals Wa, Wb, Wc, which are set so as to obtain the partitioned hollow layers to be obtained. Wd, We, Wf, Wg, Wh are selected. The intervals Wa to Wh may each be a fixed reference width, that is, a unit length, or may be a predetermined arbitrary width. For example, when a sealed hollow layer is filled with a sealing gas, for example, an inert gas such as dry air, argon gas, krypton gas, or helium gas, the maximum heat insulation effect can be obtained depending on the type of the sealing gas. It is preferable to set the position of the intermediate plate holding portion formed on the frame member 13 so that the thickness of the gas layer has an optimum range and a plurality of sealed gas layers in the optimum range are obtained. In this case, as described above, this position is preferably set with reference to the position of the central portion of the groove-shaped portions of the intermediate plate holding portions 16a to 16g.

  For example, when the intervals Wa to Wh are the same unit length, in a certain filled gas, the maximum heat insulation property is obtained when the gas layer thickness is (Wa + Wb), (Wc + Wd), (We + Wf), (Wg + Wh). When the effect is obtained, the three intermediate plates 15 may be disposed using the groove portions of the intermediate plate holding portions 16b, 16d, and 16f. In addition, when two kinds of sealing gases are used, the thickness of the gas layer is (Wa + Wb + Wc) and (Wf + Wg + Wh) in one sealing gas, and the maximum heat insulating property is (Wd + We) in the other sealing gas. When the effect is obtained, the two intermediate plates 15 may be disposed using the groove portions of the intermediate plate holding portions 16c and 16e.

  The interval between the center positions of the groove-shaped portions of the intermediate plate holding portion is preferably set to a predetermined unit length so that it can be appropriately selected and used according to the sealed gas to be used. For example, the unit length can be set to a certain value in the range of about 5 mm to 10 mm, so that the correspondence to the sealed gas to be used can be enhanced.

  By using a frame member in which a predetermined number of rows of groove-shaped portions are provided in advance in the intermediate plate holding portion, as described above, the optimum sealing among the multiple rows of intermediate plate holding portions according to the type of the filled gas By using the intermediate plate holding portion selectively so that the thickness of the gas layer can be obtained, it is possible to obtain a multiple glass shoji excellent in heat insulation and sound insulation.

  Also in the frame member 13 shown in FIGS. 4 to 11, a synthetic resin material or an aluminum material is preferably used as the frame member 13 as in the example shown in FIG. 3. Preferred examples of the synthetic resin material for forming the frame member include hard vinyl chloride resin materials, acrylonitrile / styrene resin materials, and those in which glass fiber materials are added. Of course, these thermoplastic synthetic resin materials are used. However, various thermoplastic synthetic resin materials can also be used.

  Further, as the frame member forming material, it is more preferable to obtain a frame member composed of a single member using one kind of material, but not limited to this, a composite material using a plurality of kinds of materials is not limited. It is good also as a single member. For example, it may be a frame member of a composite structure made of different synthetic resin materials partially by co-extrusion molding, or a frame of a composite structure made of a synthetic resin material and an aluminum material as described above. It may be a member. Such a composite structure can be obtained by integrally molding a desired frame member forming material. In particular, when a frame member having a spacer portion or a frame member 18 having a spacer portion and a vertical saddle portion integrally formed with a hard vinyl chloride resin material or acrylonitrile / styrene resin material is used as a shoji, It is more preferable because it is excellent in heat insulation and durability, is inexpensive, has a high heat insulation effect, does not easily condense, and can provide a multiple glass screen with excellent sound insulation.

  In addition, when the frame member 13 is formed of a hard vinyl chloride resin material or other synthetic resin material, the outer surface side portion S of the frame member 13 is formed to prevent moisture permeation from the outside of the frame member 13. The moisture permeation preventive film such as an aluminum foil can be attached as in the example of FIG.

  Moreover, although the example shown in FIGS. 4-11 demonstrates the structure of the frame member of the lower side of a multiple glass shoji, the frame member of the upper side of a multiple glass shoji, the frame member of a left side, the right side In the same manner as in the example of FIG. 3, it is more preferable that the frame member basically has the same structure as the frame member on the lower side. Of course, an appropriate structural change may be made according to the specifications of the frame members on the upper side, the left side, and the right side of the multiple glass shoji.

  In addition, when the space portion 23 is formed in the frame members on the four sides of the multiple glass shoji, the desiccant can be filled only in the frame members on the necessary sides among the four sides or only in the necessary portions as shown in FIG. Same as the case.

  As an adhesive material (first sealing material and second sealing material) used for bonding the glass plate used in the multiple glass shoji of the present invention and the side part of the frame member that comes into contact, a glass plate Considering simplification of the bonding process between the glass plate and the frame member so that excellent bonding strength, moisture permeation prevention, durability, good bonding surface, etc. can be obtained between the frame and the side of the frame member Thus, an appropriate adhesive is used. For example, when the side part of the frame member is made of a hard vinyl chloride resin material or an acrylonitrile / styrene resin material, the adhesive may be a silicone adhesive, a polysulfide adhesive, a butyl adhesive, or a hot melt adhesive. Epoxy adhesives, double-sided adhesive tapes, double-sided adhesive tapes and the like can be preferably used. Moreover, when a frame member is provided with a vertical hook part, also as an adhesive used for adhesion between a glass plate and a vertical hook part, as described above, excellent adhesion between the glass plate and the vertical hook part. An appropriate adhesive is used so that strength, moisture permeation prevention, durability, a good adhesion surface, and the like can be obtained, and in consideration of simplification of the adhesion process between the glass plate and the vertical flange. For example, when the vertical flange is made of a hard vinyl chloride resin material or an acrylonitrile / styrene resin material, as in the above example, the adhesive may be a silicone adhesive, polysulfide adhesive, butyl adhesive, hot A melt adhesive, an epoxy adhesive, a double-sided adhesive tape, a double-sided adhesive tape, etc. can be preferably used. The adhesive may use a primer for the purpose of improving the adhesive force as necessary.

Thereby, dew condensation of the hollow layers 44a, 44b, 44c, 44d can be prevented, and a multiple glass shoji excellent in moisture resistance can be provided.

  Further, since the moisture permeation preventive layer 86 is not exposed from the surface of the multiple glass shoji and is interposed between the spacer portion 46 and the flange portion 53, the moisture permeation preventive layer 86 is formed by the spacer portion 46 and the flange portion 53. Can be protected. Thereby, the moisture resistance of the multiple glass shoji can be maintained over a long period of time.

  The moisture permeation preventive layer 86 is preferably a layer formed by applying a moisture permeation preventive paint and cured, and a layer formed by attaching a moisture permeation preventive film.

  Typical examples of the moisture permeation preventing paint include a fluororesin paint and a polyvinylidene chloride resin paint.

Further, the moisture permeation-preventing film-like body includes a metal-coated film having a moisture permeation-preventing performance, a ceramic coating film, a composite coating film of metal and ceramic, a metal tape, and a film made of a resin having a moisture permeation-preventing performance. A moisture prevention resin film or a moisture permeation prevention resin coating film is mentioned. For example, a typical example of the metal-coated film is an aluminum-coated film obtained by coating a plastic film carrier with aluminum having moisture permeation prevention performance by means of a vacuum deposition method, a sputtering method, or the like. A typical example of the ceramic-coated film is a ceramic-coated film obtained by coating a plastic film carrier with a metal oxide (for example, SiO ₂ ) having moisture permeation-preventing performance by means such as vacuum deposition or sputtering. It is done. Moreover, as a metal tape, an aluminum metal tape and a stainless metal tape are mentioned as a typical example. Typical examples of the moisture permeation preventing resin film include a fluororesin film and a polyvinylidene chloride film.

  In the embodiment shown in FIGS. 17 to 19, the spacer portion 46 and the flange portion 53 are separated from each other, but the spacer portion 46 and the flange portion 53 may be configured as a separated type. When the spacer portion 46 is a separation type, a plurality of hard sponges may be used to separate the glass plates.
